Abstract

&lt;I&gt;Background.&lt;/I&gt; Subjective memory and concentration difficulties
are frequently expressed in modern society and, if sufficiently
worrying, may elicit a medical consultation for elucidation.
When a clear explanation cannot be given, a neuropsychological
assessment may be a useful tool.
&lt;br&gt;&lt;I&gt;Method.&lt;/I&gt; The present naturalistic study recruited 20 patients
who reported cognitive difficulties for which a medical explanation
could not be found. Each subject underwent a clinical
interview and neuropsychological assessment in order to identify
the nature and severity of the problem, and to identify a
possible cause of these complaints.
&lt;br&gt;&lt;I&gt;Results.&lt;/I&gt; Several possible explanations were documented but
mood disturbance was considered the most likely reason for
the identified cognitive difficulties.
&lt;br&gt;&lt;I&gt;Limitations.&lt;/I&gt; This was a naturalistic study with a specific sample,
and consequently generalisability may be reduced.
&lt;br&gt;&lt;I&gt;Conclusion.&lt;/I&gt; Even in episodes of mild depression cognitive difficulties
occur that may be presented to neurologists rather than
psychiatrists. In such instances the patient is at risk of not receiving
the appropriate treatment for his or her mood disorder.
